Bertha the Tunneling Machine

Join us for Bertha’s Pre-Bore Dedication Event

In just a few weeks, Bertha the Tunneling Machine will begin digging the SR 99 tunnel beneath the city. To mark the occasion, Gov. Inslee, WSDOT and Seattle Tunnel Partners invite you to join us in saying bon voyage to Bertha at a dedication ceremony and public event.

Dedication ceremonies for these amazing machines are a long-running tradition within the tunneling industry, and we look forward to sharing this tradition with the people of Washington. The celebration begins at 11:30 on Saturday, July 20 at Bertha’s launch pit, with brief speeches and a dedication ceremony. When the ceremony ends, you’ll have an opportunity to walk the construction site and peer down at Bertha, poised and ready to dig, in her 80-foot-deep launch pit. Also, don’t miss this chance to sign your name on a tunnel liner segment before they are installed as the tunnel walls. Food trucks will be on-site for snack purchases. This is a once-in-a-lifetime chance to see the five-story-tall machine up close before it begins tunneling beneath Seattle.  Please take note of the “conditions of entry” listed below, including the requirement that attendees must wear flat, closed-toe shoes (no sandals, flip-flops or high-heels.)
